Transport system in plants

The transport system of plants consists of the xylem and the phloem. The xylem transports minerals and water from the root to all aerial parts of the plant. The phloem transports the food ( glucose, etc). from the leaves to other parts of the plant where it is either consumed or stored. Though the plants have a transport system, they do not have a separate digestive or excretory system.
